This invention relates to the anchoring of sta les in work into which they are driven an in different as ects provides a novel method and a nove product, this application being a division 0 a copending application Serial No. 129,425, filed on August 16, 1926. y

In Letters Patent No. 1,742,502, granted upon an earlier ap lication of mine on J anuary 7, 1930, I disc osed and claimed a novel method of anchoring staples b deflecting or curving the legs of each stap e laterally of the cross-bar, i. e., transversely of the plane determined by the le s and the cross-bar before the bending 0 the legs takes place,

through force ap lied at the same side of the Work from whic the staple is driven, thus causing the legs to follow curved aths in the work such as to anchor them wit out the need of clinching them on any surface of the work. As applied, for example, to the manufacture of shoes of that type in which the outsole is fastened to the insole by stitches that penetrate through both the out-- sole and the insole, frequently termed through-and-through stitches, that method is especially advantageous in the fastening of out the upper 1n lasted position on the outer or bottom face of the insole along the sides of the shoe, since by its use the upper may be fastened by staples so anchored as to avoid the 1presence of clinched metallic fastenings e inner face of the insole in the locations of the side-lasting tacks that have been commonly used in making shoes of that type.

The present invention provides a novel method affording increased insurance that a staple anchored without clinching, for example in the manner above described, w ll successfully resist all strains tending to with draw it from the work, either as applied to the fastening of uppersto soles or insoles or in more general relations. In accordance with the novel practice herein illustrated the legs of the staple, while bein driven and curved laterally of the crossar, are also relatively deflected lengthwise of the crossbar. This is conveniently accomplished, as herein shown, by the use of suitable guiding grooves provided in the deflecting member which acts to curve the legs laterally of the cross-bar, so that the legs are relatively deflected by the rooves lengthwise of the cross-bar while t ey are beingadriven and curved. The staple is thus anchored in the work by the combined efl'ect of the curvature of the legs laterally of the cross-bar and their relative deflection lengthwise of the crossbar. As herein illustrated both legs are thus deflected and the deflection is such as to s read the legs apart, but the invention is not limited to that partlcular manner of treatment.

In addition to its novel method aspects, the invention further presents novelty in a shoe provided with staples anchored as described for fastening the upper in lasted relation to the sole or insole, and in a still more general aspect novelty also in work comprising a lurality of layers of material fastened toget er by such a staple or staples.

The invention Wlll now be more particularly described by reference to the accompanyin drawings and thereafter pointed out in t e claims. In its method aspects the invention is herein illustrated by reference to mechanism adapted for usein ractising the method in the lastin of s oes, that mechanism being more fulFy shown and described in the co ending application of which this application is a division.

In the-drawings,

Fig. 1 is a sectional view of a portion of the mechanism above referred to and of a shoe under treatment, illustrating especially how the legs of the staple are curved laterally of the cross-bar;

Fig. 2 is a view on an enlarged scale of the enlar ed scale il-;

away to show the other leg in full; and t Fig. 4 is a sectional view showing a portion of a completed shoe of the throughand- ,site to the end of the staple-guiding through sewed type having its upper materials secured to the insole in lasted position b staples anchored in the manner provided by this invention.

As more fully disclosed in the above-mentioned application of which this is a division, the mechanism shown in Fig. 1. comprises an edge gage 10 and a bottom rest 12 in enga ement with which a shoe in the hands 0% an operator is presented as illus trated, the shoe being moved by the operator to permit the lasting of difi'erent portions thereof successively. In each lasting position of the shoe the upper materials (hereinafter frequently referred to inclusively as the upper), comprising as shown the u per leather a and the lining b, are pulled y a grip or (not shown) and are then laid inwar ly over the insole c by mechanism including a carrier 14 which is moved in a direction inclined to the plane of the-insole, the carrier having thereon a staple-guiding nozzle a portion of which is' shown at 16. The staple for fastening the upper to the insole is referably formed with legs that are straight before the staple is driven, the legs and the cross-bar then lying in the same" plane, as in the common form of staple, and the staple is driven from the nozzle 16 by a driver 18 moving in a direction inclined to the bottom face of the insole. As the staple is thus driven its legs (1 are engaged by a deflecting member 20 mounted on the carrier 14 with its lower end in a position oppopassage in the nozzle 16. The staple legs are thus engaged by the deflecting member 20 at the same side of the work from which the staple is driven, i. e., without the presence of any portion of the work between the deflecting member and the staple nozzle, and by the action of the deflecting member different portions of the legs are curved successively in the driving operation in directions laterall of the cross-bar e and both at the same s1de of the cross-bar before the different res ective ortions enter the work. As herein ustr'ate the staple is driven in a direction inclined inwardly from the edge of the insole with the cross-bar substantially parallel to the insole edge, and the legs are so deflected that they enter the shoe in directions a p roximately perpendicular to the bottom ace of the insole and then follow curved paths leading back toward that surface of the work at which they entered, or indirections substantially opposite to that of the drive, so that they are anchored in the body or intact substance of the insole with their ends directed reversely toward the outer or bottom face of the insole. The legs are preferably curved, as illustrated, in such degree asnot to netrate the inner face of the insole. Their ends may or may not emerge from the bottom face of the insole, since, if they do so emerge, they will be covered by the outsole; and there is, in any event, no danger that the ends of the legs will work up into the interior of the shoe in the wear of the shoe. It will be further noted that, with the staple driven in a direction inclined inwardly from the edge of the insole, as illustrated, the legs are curved outwardly toward the edge of the insole. As thus far described the manner of anchoring the staple in the work is substantially such as disclosed in the above-mentioned Letters Patent.

In order to increase the holding power of the legs of the staple in the work, and thus to afford furtherinsurance that the staple will not be loosened in the work by the strain thereon, this invention provides for eflecting a relative deflection of the legs lengthwise of the cross-bar. This may be conveniently accomplished, as shown, by the use, of non-parallel guideways or grooves 22 (Fig. 2) in the staple-engaging face of the deflecting member 20 to receive and guide the legs of the staple as they are being driven and curved in the manner hereinbefore described. These grooves, as herein illustrated, are so arranged that each of the legs is deflected in a direction away from the other leg, the legs thus being s read apart as they are driven so that they lverge fromeach other in the work. The shape of the staple after it has been driven is illustrated in Fig. 3. While I believe it to be preferable thus to deflect both legs in such manner as to spread them apart, the invention is not limited to this particular manner of treatment. The extent of the deflection also may be varied as desired by suitable arrangement of the grooves 22.

Fig. 4. shows a portion of a completed shoe of the type illustrated, i. e., a shoe in which the outsole f is secured to the insole c by stitches 9 that pass through both the outsole and the insole, frequently termed throughand-through stitches. It will be observed that the staples, driven and anchored as hereinbe fore described in the side-lasting of the shoe, remain as permanent arts of the shoe. A shoe thus made, while ee from metallic fastenings clinched on the inner face of the insole along the sides of the shoe, like that disclosed in the above-mentioned Letters Patent, is further improved by reason of the increased insurance against loss of shape in the interval between the lasting of the shoe and the fastening of the outsole to the shoe due to the security of the connection between the upper and the insole aiiorded by the relative deflection of the legs of each lasting staple lengthwise of the cross-bar in addition to their curvature laterally of the cross-bar.

While the invention is herein illustrated and described with particular reference to the fastening of uppers to insoles in the manufacture of shoes of the through-'and-through sewed ty e, it is considered that in various as sets t e method disclosed may be utilized a vantageously for fastening uppers in the manufacture of shoes of other t es, and the term sole is accordingly use in man of the claims in a comprehensive sense to inc ude both the insole of certain types of shoes and also that part which in shoes of other t es may be the outsole or the only sole with w ich the shoe is provided. Furthermore, it is considered that in a more general aspect the in-' vention is not limited in utility to the fastening of uppers nor, in fact, to shoe manufacture.
